Call to service program functions don't have %PARMS() set properly - ie with *NOPASS parameters and

from xmlservice.

Take this with a grain of salt because I can't actually use the system debugger on the XMLSERVICE right now, but FWIW I think the service program calls either need a SETALLEN before the prototyped call or use SETALLEN & CALLX instead of the prototype call.

Also it might be possible to use CALLPGMV with a service program function but I wasn't sure based on the IBM documentation for it. If you can do that it would be very similar to the call *PGM stuff instead of doing something totally different.

Update: It turns out that the service program is being called via the PASE functions, not the ILE functions as I originally thought. It's ultimately using Qp2CallPase(). The RPG documentation at https://www.ibm.com/docs/en/i/7.3?topic=functions-parms-return-number-parameters indicates that %PARMS needs an operational descriptor to be passed but I haven't found anything yet that indicates how one might do that from "another ILE language". Even though the XMLSERVICE is actually RPG that caveat applies because it's not calling things the normal way a regular RPG program would.

Does anybody know if we converted the Qp2CallPase() calls to use _ILECALLX would it be possible to somehow generate the operational descriptor that RPG needs to support %PARMS? Ie maybe if the argument list is prepared with build_ILEarglist() first?

With the latest comment on the NodeJS iToolkit issue it seems like this is not possible to fix without IBM i Idea 3080 (https://ibm-power-systems.ideas.ibm.com/ideas/IBMI-I-3080) being implemented.
